The Presage® Assay

The Critical Diagnostics Presage® ST2 Assay kit is an in vitro diagnostic test that quantitatively measures ST2 in serum or plasma by enzyme-linked immunosorbant assay (ELISA) in a microtiter plate format. The Presage® ST2 Assay is indicated to be used in conjunction with clinical evaluation as an aid in assessing the prognosis of patients diagnosed with chronic heart failure.

The Presage® ST2 Controls, Level 1 and Level 2, are designed to be used for monitoring the performance of test procedures on the Critical Diagnostics Presage® ST2 Assay kit.

The assay is calibrated with seven standards spanning the range of 3.1 to 200.0 ng/ml. The standard ST2 analysis cutpoint is 35 ng/ml.

Use of ST2 in Conjunction with Traditional clinical evaluations

ST2, and other clinical biomarkers, such as natriuretic peptides, are measures of separate and distinct biological processes. In conjunction, they provide independent and complementary prognostic information. Consult the Indication For Use manual for more information.
